HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.5% (FIRST EPSS); higher than 85% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: sendmail (Debian:12) 8.13.1-13; sendmail (Debian:3.0) 8.12.3-7.1.

Low priority for now. Upgrade to sendmail (Debian:12) 8.13.1-13; sendmail (Debian:3.0) 8.12.3-7.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Sendmail before 8.12.3 on Debian GNU/Linux, when using sasl and sasl-bin, uses a Sendmail configuration script with a fixed username and password, which could allow remote attackers to use Sendmail as an open mail relay and send spam messages.
